平面上沉积微相中以边滩、河道边缘、河漫沉积为主，砂体呈席状、条带状、豆荚状等，分叉、交叉频繁，厚度变化较快沉积微相对储层物性和剩余油分布具有控制作用，该区沉积微相模型的建立对储层非均质性研究及控水稳油和寻找剩余油气具有重要意义关键词关键词：沉积特征；相模式；微相类型；馆上段；孤东油田二区中国石油大学胜利学院本科毕业设计（论文）ABSTRACTIn this paper, core and slice through observation, particle size analysis, logging data interpretation and other means, Guantao Gudong Oilfield as sedimentary facies were studied. Well connected through to the single well and integrated facies analysis and geological data related to the establishment of the isolated East Oilfield as in the upper sedimentary facies model, illustrates the region microfacies distribution and evolution, revealing the sedimentary microfacies reservoir properties, the remaining oil distribution of the important control function. The results show that: the area-steps developed in the upper river and the lower part of the braided river facies model of two, with river facies, subfacies embankment, River Man subfacies and abandoned channel facies of four sub-facies, with beach side , channel deposits, the heart beach facies, bottom sediment retention, river edge, crevasse splay, floodplain deposits located between depression and 8 kinds of sedimentary facies. Micro-phase deposition plane to side beach, river edge, river diffuse deposits in the sand takes the shape of sheet, strip, pod-like, etc., bifurcation, cross-frequent changes in the thickness of fast. Sedimentary microfacies Reservoir and the remaining oil distribution is controlled, the district sedimentary facies model of the reservoir heterogeneity and control oil and water stability is important to find the remaining oil and gas.
